Revert "RDMA/usnic: use iommu_map_atomic() under spin_lock()"

Browse Source 
This reverts commit 80282a3d10 which is
commit b7e08a5a63a11627601915473c3b569c1f6c6c06 upstream.

It will not build as a pre-requsite commit was reverted as it broke the
Android kernel abi and it was needed for this change.  This change is
not needed for Android systems so it is safe to revert.
